The closed-form expressions for CCK modulation performance were derived from correlation demodulation according to the complementary code properties and CCK modulation regulation.
This paper discusses the theory and the realization approach of BOC modulation and demodulation in satellite navigation system, and focuses on the BOC code tracking technology.
